Translation is a symmetry pattern created by stamping one element across a page at regular intervals while keeping its orientation unchanged. Repetition helps viewers spot relationships and patterns. section 2.2.4 section 2.3
Use translation when:
- Small-multiples graphs repeat a simple chart for many categories, such as countries or companies. section 2.2.4
- Relative differences matter more than precise values, because repeated charts make patterns visible but can hide detail. section 2.2.4
- Typography repeats consistent styles, sizes, and placements to establish a hierarchy of importance. section 5.4.5
A practical visual example
A gender- and ethnicity-disparities visualization uses repeated chart structures and recurring label styles. Matching labels signal matching importance, while the repeated charts invite comparisons across categories. section 2.2.4 section 5.4.5

Inspect the translation example to see how repeated visual elements preserve orientation while supporting comparison. section 2.2.4
